4 channel measurement instrument for QMB and SAW sensors

4 channel measurement instrument for QMB and SAW Sensors up to 500MHz.

  • Frequency input up to 500 MHz
  • Simultaneous, continuous measurement of all channels
  • Control port for external oscillators and temperatur and humidity sensor
  • Digital IO for synchronisation
  • Optional interfaces:Ethernet 10/100MBit
    WLAN 802.11.b with WPA2
    Telegesis IEEE 802.15.4 wireless sensor network with mesh network stack


Flexible research platform

External oscillators are connected to the FQ4 instrument via SMA cables. The oscillator control port provides +3.3V power and control to the oscillators. Additionally a Sensirion SHT humidity and temperature sensor can be connected to the oscillator control port.

External oscillators

A variety of external oscillators for QMB and SAW sensors is currently under development and will be available soon. Oscillators can be tailored to meet your requirements.

Software support

Drivers can be provided for Windows 2000, XP, Vista and Linux. A DLL allows for easy integration into custom measurement software. Optionally the interface may be mapped to a virtual serial port. Custom software development services are available at JLM Innovation.

Compatible with MultiSens

MultiSens is an integrated software package for measurements of sensor arrays with integrated data analysis and pattern recognition algorithms.
